2016-08-19Avoid confusing GCC 4.2.1 by saying "int foo()... inline int foo() {...}"Nick Mathewson
Fixes bug 19903; bugfix on 0.2.8.1-alpha.

2016-08-11Only use evutil_secure_rng_add_bytes() when present.Nick Mathewson
OpenBSD removes this function, and now that Tor requires Libevent 2, we should also support the OpenBSD Libevent 2. Fixes bug 19904; bugfix on 0.2.5.4-alpha.
2016-08-11Fix a bug in the old-gcc version of ENABLE_GCC_WARNINGNick Mathewson
Fixes bug 19901; bugfix on 0.2.9.1-alpha.

Remove or adjust as appropriate.
2016-08-02Bufferevent removal: remove more bufferevent-only optionsNick Mathewson
(All this IOCP stuff was bufferevent-only.)

2016-07-28Three more -Wshadow fixes.Nick Mathewson
2016-07-28Fix a huge pile of -Wshadow warnings.Nick Mathewson
These appeared on some of the Jenkins platforms. Apparently some GCCs care when you shadow globals, and some don't.
2016-07-28Merge branch 'bug18902_squashed'Nick Mathewson
2016-07-28Fix all -Wshadow warnings on LinuxNick Mathewson
This is a partial fix for 18902.
2016-07-26Fix an integer overflow related to monotonic time on windows.Nick Mathewson
To maintain precision, to get nanoseconds, we were multiplying our tick count by a billion, then dividing by ticks-per-second. But that apparently isn't such a great idea, since ticks-per-second is sometimes a billion on its own, so our intermediate result was giving us attoseconds. When you're counting in attoseconds, you can only fit about 9 seconds into an int64_t, which is not so great for our purposes. Instead, we now simplify the 1000000000/1000000000 fraction before we start messing with nanoseconds. This has potential to mess us up if some future MS version declares that performance counters will use 1,000,000,007 units per second, but let's burn that bridge when we come to it.
2016-07-26Add a function to simplify a fraction.Nick Mathewson
Apparently remembering euclid's algorithm does pay off sooner or later.

2016-07-26Tweaks on 19435 fix:Nick Mathewson
* Raise limit: 16k isn't all that high. * Don't log when limit exceded; log later on. * Say "over" when we log more than we say we log. * Add target version to changes file

2016-07-21Coverity hates it when we do "E1 ? E2 : E2".Nick Mathewson
It says, 'Incorrect expression (IDENTICAL_BRANCHES)' Fix for CID 1364127. Not in any released Tor.
2016-07-21loony mingwcross bug: insist we dont have clock_gettime.Nick Mathewson
2016-07-21fix monotime test mocking on 32-bit systemsNick Mathewson
2016-07-21Actually make monotonic time functions mockable.Nick Mathewson
This is different from making the functions mockable, since monotime_t is opaque and so providing mocks for the functions is really hard.
2016-07-21Revert "Make the monotonic{_coarse,}_get() functions mockable."Nick Mathewson
This reverts commit 2999f0b33fec8e91ba8e4680d3f9d03b09fe9501.

2016-07-19convert timers.c to use real monotonic time.Nick Mathewson
2016-07-19Basic portable monotonic timer implementationNick Mathewson
This code uses QueryPerformanceCounter() [**] on Windows, mach_absolute_time() on OSX, clock_gettime() where available, and gettimeofday() [*] elsewhere. Timer types are stored in an opaque OS-specific format; the only supported operation is to compute the difference between two timers. [*] As you know, gettimeofday() isn't monotonic, so we include a simple ratchet function to ensure that it only moves forward. [**] As you may not know, QueryPerformanceCounter() isn't actually always as monotonic as you might like it to be, so we ratchet that one too. We also include a "coarse monotonic timer" for cases where we don't actually need high-resolution time. This is GetTickCount{,64}() on Windows, clock_gettime(CLOCK_MONOTONIC_COARSE) on Linux, and falls back to regular monotonic time elsewhere.

2016-07-11Add (SOCK_DGRAM, IPPROTO_UDP) sockets to the sandboxing whitelistPeter Palfrader
If we did not find a non-private IPaddress by iterating over interfaces, we would try to get one via get_interface_address6_via_udp_socket_hack(). This opens a datagram socket with IPPROTO_UDP. Previously all our datagram sockets (via libevent) used IPPROTO_IP, so we did not have that in the sandboxing whitelist. Add (SOCK_DGRAM, IPPROTO_UDP) sockets to the sandboxing whitelist. Fixes bug 19660.
2016-07-09Adds missing syscalls to seccomp filter.Daniel Pinto
Fixes #18397 which prevented tor starting with Sandbox 1.
2016-07-08Move our "what time is it now" compat functions into a new moduleNick Mathewson
I'm not moving our "format and parse the time" functions, since those have been pretty volatile over the last couple of years.
